Clean terminals with electrical contact cleaner and apply dielectric grease.

Both refer to the identical 4-pin alternator regulator housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Does this fit Denso alternators on non-Toyota\/Honda vehicles?\u003c\/strong\u003e\u003cbr\u003eA: Denso supplies alternators to many OEMs. If your alternator uses a 4-pin regulator connector matching the 6189-0694 housing dimensions, this connector will fit. Verify pin count and housing shape before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What causes the battery light to come on after replacing the alternator?\u003c\/strong\u003e\u003cbr\u003eA: In many cases, the alternator itself is fine but the regulator connector has failed. A corroded or loose 6189-0694 connector will cause the same symptoms as a failed alternator. Always inspect the connector first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What crimping tool is needed?\u003c\/strong\u003e\u003cbr\u003eA: Use a ratchet crimper for 0.5mm² (18 AWG) Yazaki-series terminals. The Hozan P-706 or Engineer PA-09 are commonly used for this terminal series.\u003c\/p\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cp\u003e1 × 4-Pin Female Connector (6189-0694 \/ 90980-11964) with 18 AWG wire and terminal insert\u003c\/p\u003e","brand":"Cable Parts Online","offers":[{"title":"4P \/ Female with Wire \/ China Mainland|Line Connector|3 Sets","offer_id":47844185112821,"sku":"14:200004889#Female with Wire;200001249:202408832#3 Sets;200007763:201336100;200497261:200000933;462:203053809","price":43.35,"currency_code":"USD","in_stock":true},{"title":"4P \/ Female with Wire \/ China Mainland|Line Connector|10 Sets","offer_id":47844185145589,"sku":"14:200004889#Female with Wire;200001249:202408829#10 Sets;200007763:201336100;200497261:200000933;462:203053809","price":144.6,"currency_code":"USD","in_stock":true},{"title":"4P \/ Female with Wire \/ China Mainland|Line Connector|1 Set","offer_id":47844185178357,"sku":"14:200004889#Female with Wire;200001249:202408830#1 Set;200007763:201336100;200497261:200000933;462:203053809","price":14.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3494\/0149\/files\/Sb1d8926ec4ec423f8909b81dde2671daI.webp?v=1773810027","url":"https:\/\/www.csldmcml.com\/products\/4-pin-denso-alternator-connector-6189-0694-90980-11964-honda-toyota","provider":"Cable Parts Online","version":"1.0","type":"link"}
